Details and patient eligibility

About

The aim of the study is to compare the efficacy of Paclitaxel-eluting PTCA-balloon dilation (SeQuentTM Please) followed by cobalt-chromium stent (CoroflexTM Blue) deployment versus Paclitaxel-eluting stent (TaxusTM LibertéTM) deployment in the treatment of de-novo-stenoses in native coronary arteries (reference diameter:more then 2.5 mm and below 3.5 mm, length of stenosis ≥ 10 mm ≤ 20 mm) of patients with diabetes mellitus for ≥ 3 years for procedural success and preservation of vessel patency.

This study is a prospective, randomized, multi-center, two-armed phase-II pilot study conducted in Malaysia and Thailand.

128 diabetes mellitus patients shall complete the study per protocol after random assignment to either of the treatment groups on the order of 20 to 50 patients per center.

Diabetes mellitus patients with stable or selected forms of unstable angina or documented ischemia due to a de-novo stenosis in a native coronary artery will be enrolled. Vessels may not supply an entirely infarcted myocardial area.

Late lumen loss at 9 months is the primary endpoint.

Inclusion criteria

History of diabetes mellitus of at least 3 yrs prior to enrollment. Diabetes mellitus may be treated either orally or s.c.
Stable blood glucose level for the 6 months preceding enrollment as reflected by HbA1c concentrations measured exclusively ≤ 8 %
Patients with stable angina pectoris (CCS class 1-3) or with unstable angina pectoris (Braunwald class 1-2, A-C) or documented ischemia or with documented silent ischemia
Patients eligible for coronary revascularization by means of PCI
Women of childbearing potential may not be pregnant nor have the desire to becoming pregnant during the first year following the study procedure. Hence, patients will be advised to use an adequate birth control method up to and including 6 months follow-up
Patients who are mentally and linguistically able to understand the aim of the study and to show sufficient compliance in following the study protocol
Patients must agree to undergo the 9 months angiographic follow-up
Patients must agree to undergo the 3 year clinical follow-up
De-novo native coronary artery stenosis (reference diameter: ≥2.5 mm and ≤ 3.5 mm, length of stenosis: ≥ 10 mm and ≤ 20 mm)
Target lesion is ≥ 3 mm distant from a major side branch (> 2.0 mm in diameter) and ≥ 3 mm form a previously deployed stent of any type (including active and passive coatings, bare metal stents)
The target lesion must be treated with a single stent only (multiple stenting shifts the patient to the intention-to-treat group)
Single or multi-vessel coronary artery disease

Exclusion criteria

Patients with acute (< 24 h) or recent (48 hours) myocardial infarction
Patients with unstable angina pectoris (Braunwald class 3)
Patients with severe congestive heart failure
Patients with severe heart failure NYHA IV
Patients with severe valvular heart disease
Women who are pregnant or lactating
Patients with another coronary stent implanted previously into the target vessel, drug eluting stents less than 9 months and bare metal stents or stents with passive coatings less than 3 months before the PEPCAD IV DM PCI
Patients with bleeding diathesis in whom anticoagulation or anti-platelet medication is contraindicated
Patients who had a cerebral stroke < 6 months prior to the procedure
Patient participates in other clinical trials involving any investigational device or drug
Untreated hyperthyroidism
Patient has presence or history of severe renal failure (GFR<30ml/min) and is therefore not eligible for angiography. Patient's serum creatinine levels must be documented
Post transplantation of any organ or immune suppressive medication
Other disease to jeopardize follow-up (e.g., malignancy)
Addiction to any drug or to alcohol
Patients with any type of surgery during the week preceding the interventional procedure.
Therapy with anticoagulants
Poorly controlled diabetes mellitus as reflected by an HbA1c ≥ 8% during the six months prior to enrollment in PEPCAD IV DM
Patient has a history of peptic ulcer or gastric/intestinal bleeding during the past 6 months.
Evidence of extensive thrombosis within target vessel before the intervention
Side branch > 2 mm in diameter originating from the lesion
Stent within the same vessel less than 3 mm distant from target lesion
Multi-lesion percutaneous coronary intervention within one vessel (PCI of a total of two lesions one each in a different vessels is permitted)
Target lesion located in any type of coronary bypass (i.e., venous graft, arterial bypass) or graft/native artery connection
Coronary artery occlusions of any type (e.g., acute or chronic)
In-stent restenosis
In-segment restenosis of the native vessel within 4 mm adjacent to the target lesion
